Small discovery of the day: Algorithmic Markup in one plugin interprets the meaning of the remainder of the page which should be designed with this cooperation in mind. See Visitor as Schema
Browsing works as well as it does because the browser overlaps many requests. This turns out to be especially true for the dynamic diagrams recently added via algorithmic markup in Graphviz plugin. Our goal has always been to explore a region of the wiki by following all of the links on a page at once. We've now enabled this mechanism with a deceptively small code change.
The Graphviz plugin accepts an unusual dialect of markup which is really a computer algorithm for visiting pages and drawing what it finds. We'll explain this in simple terms that should get one going quickly.
